Another argument against marxism, in case you needed one. People who do not produce, but rather understand how to organise purely social connections, even within a socialist society are instrumental to connecting humans with problems with humans who produce solutions to these problems. I'm not talking about marketing departments here and I'm not talking about marketing channels either.
I'm talking about people who understand how various social value-add activities work and spend at least 20 hours a week socialising within the circles of producers.
Marxism says that these people are the epitomy of bourgeoisie: they aren't even managers. But who do you think drive social innovation if not them?
As a proletarian producer, morally, I owe a person like this some goods, services or money for them helping their network learn about my solution to their problem.
Of course, everything has a rotten evil twin version. A rotten evil twin version of this are influencers, but it is not an argument for ELIMINATION of human beings, it's not an argument for calling certain kinds of people "parasites" and other things that the hateful ideologies like communism advocate.
